Description

Technical Field

[0001] The present invention relates to the technical field of coal mine machinery, and particularly relates to a folding support transportation device and a method for disassembling, assembling and transporting supports, which are suitable for transporting single-column or two-column unit supports. Background Art

[0002] Roadway hydraulic supports are important support equipment in the process of coal mining, and are used to support the two roadways of the working face. With the gradual increase in the intensity of coal mining in China, the required support range of the two roadways of the working face gradually increases, and the support strength gradually increases. Especially for rock burst mines, the support distance of the two roadways should reach 70m to 200m. However, as the working face moves forward, the roadway supports also need to move forward continuously. There are two ways to move roadway supports: one is that all the supports supported in the roadway move forward in sequence, which is called the sequential support moving method; the other is to remove the support at the end of the roadway near the working face and move it to the far end of the working face and then re-support it, which is called the large-cycle moving method.

[0003] The sequential support moving method is easy to implement in terms of the structure of the supports. Usually, a pushing mechanism is added between adjacent supports. However, this method requires all the supports to be unloaded and moved and supported again in sequence. The moving distance of each support is relatively small, which causes the supports to repeatedly support the roadway roof, resulting in damage to the roadway roof and increasing the support difficulty of the roadway. The more supports there are, the more times the roof is repeatedly supported, and the more serious the damage to the roadway is. Therefore, the sequential support moving method is usually used in working conditions with a short support distance, usually the support length is less than 50 meters.

[0004] As the working face advances, the large-cycle moving method only requires the last support in the roadway to move to the front end of the support, and the other supports remain in the supporting state unchanged. This avoids the repeated support of the roadway roof by the supports, which is very beneficial to protecting the roadway. However, the support needs to move a long distance, and the support to be moved needs to pass through the roadway range supported by the supports, which has more restrictions on the structure of the supports. Therefore, this method is usually used in long-distance roadway support working conditions, usually the roadway support length is greater than 50 meters, and it is mainly applied to single-column or two-column unit supports.

[0005] For rock burst mines, since the roadways of the working face are usually the areas where rock bursts occur, the prevention and control system requires that the support range of all roadways in rock burst mines shall not be less than 70 meters, and the support range in severely affected areas shall not be less than 120 meters, and some even need to be supported for more than 200 meters. Therefore, the long-distance movement of the supports has become the main problem in roadway support. Especially when the roadway floor is uneven, the unit supports with a small base area are prone to tipping, which brings difficulties to the support movement. Summary of the Invention

[0006] The object of the present invention is to solve the technical problems existing in the long-distance support movement in the existing large-loop movement mode. The present invention provides a folding support transportation device and a method for disassembling, assembling and transporting the support.

[0007] The technical solution adopted by the present invention is as follows:

[0008] On the one hand, the present invention provides a folding support transportation device, which includes a base and a folding jack. One end of the folding jack is hinged to one end of the base, the other end of the folding jack is detachably hinged to the upper part of the support to be moved, and the other end of the base is hinged to the lower part of the support to be displaced.

[0009] Further, a main frame is also provided on the transportation device. One end of the main frame is rotatably hinged to the end of the folding jack, the other end of the main frame is rotatably hinged to the base, and one side of the support to be displaced is detachably fixedly connected to one side of the main frame.

[0010] Further, a turnable turning beam or telescopic beam I is hinged to one end of the base, and a towing hole or towing ring for connecting an external towing device is provided at the other end.

[0011] Further, support legs are also provided on the base. The support legs and the turning beam or telescopic beam I are respectively arranged at both ends of the base. The support legs include a connecting plate and a support rod. One end of the connecting plate is horizontally rotatably hinged to the base, the support rod is vertically arranged at the other end of the connecting plate, and the support rod is vertically arranged on the connecting plate in a liftable manner.

[0012] Preferably, the support rod is a lead screw structure, which is threadedly connected to the connecting plate for adjusting the support height of the connecting plate.

[0013] Or preferably, the support rod is a support jack for adjusting the support height of the connecting plate.

[0014] The main frame includes a main beam and a telescopic beam. The side of the main beam is used for detachably fixedly connecting with the support to be displaced.

[0015] On the other hand, the present invention also provides a method for disassembling, assembling and transporting a hydraulic support.

[0016] Step 1: Move the folding support transportation device close to the support to be displaced, control the folding jack to extend, so that its end is hinged to the upper part of the support to be displaced, and hinge the lower part of the support to be displaced to the base.

[0017] Step 2: Control the support to be displaced to contract so that its upper end is separated from the roadway roof.

[0018] Step 3, control the folding jack to contract, so that the support to be displaced rotates from the vertical to the horizontal;

[0019] Step 4, through external traction, drive the folding support transport device and the support to be displaced to move to the installation position together;

[0020] Step 6, control the folding jack to extend, so that the support to be displaced rotates from the horizontal to the vertical;

[0021] Step 6, control the support to be displaced to extend, so that its upper end forms an effective support with the roof of the roadway;

[0022] Step 7, the folding support transport device is disengaged from the fixed connection with the displaced support, and the disassembly and assembly of the support to be displaced are completed.

[0023] In the above step 1, the main frame hinged to the folding jack and the base at the upper and lower parts respectively is fixedly connected to the support to be displaced.

[0024] When performing step 1, first turn the tipping beam or the telescopic beam I to the state of contacting the roadway floor, and at the same time adjust the support rod on the support leg to the state of contacting the roadway floor.

[0025] The technical solution of the present invention has the following advantages:

[0026] A. The folding transport device provided by the present invention can fix the support to be displaced during the installation and unloading of the support, maintain the stability of the support, avoid danger during the disassembly and installation process, and has an auxiliary support function. At the same time, during the transportation process, the support to be displaced is adjusted from the vertical state to the horizontal state, reducing the center of gravity and transportation height of the support, improving the transportation stability of the support, and adapting to lower roadway transportation conditions.

The bottom surface of the base of the folding transport device provided by the present invention is a plane, and both ends are in a warped shape, which is convenient for traction to move on the roadway floor; there are support legs on the base, and the support angle and height can be adjusted.

[0034] Next, the technical solutions of the present invention will be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0035] As Figure 1 shown, the present invention provides a folding support transportation device, including a base 1 and a folding jack 2. One end of the folding jack 2 is hinged to one end of the base 1, and the other end of the folding jack 2 is hinged to the upper part of the support to be moved 6. The other end of the base 1 is hinged to the lower part of the support to be displaced 6, that is Figure 1 the structural form that does not include the main frame 3. The support to be displaced 6 here is a single-column or two-column unit support. Fixed connectors are respectively installed on the upper and lower parts on one side of the support to be displaced 6. When displacement is required, only the support to be displaced 6 needs to be retracted so that its upper end is disengaged from the support of the roadway roof. The upper end of the folding jack 2 is hinged to the fixed connector on the upper part of the support to be displaced 6, and the base 1 forms a rotary hinge with the fixed connector on the lower part of the support to be displaced 6. When the folding jack 2 is retracted, the support to be displaced 6 will rotate around the fixed connector hinged to the base at its lower part as the rotation axis, so that the support to be displaced 6 is changed from a vertical state to a horizontal state, greatly reducing its height and center of gravity position, making the transportation more stable. Of course, when the folding support transportation device is connected to the support to be displaced, it plays an effective side support role for the support to be displaced 6, avoiding dangerous problems such as tipping.

[0036] Of course, Figure 1A main frame 3 is also provided on the transportation device. One end of the main frame 3 is rotatably hinged to the end of the folding jack 2, and the other end of the main frame 3 is rotatably hinged to the base 1. One side of the support to be displaced 6 is fixedly connected to one side of the main frame 3 detachably. In this way, the two ends of the main frame 3 are respectively connected to the base 1 and the folding jack 2. During use, it is only necessary to connect the main frame 3 and the support to be displaced together through a fixed connecting piece, which is more convenient for disassembly and assembly.

[0037] In order to make the transportation device more stable in transporting the support and considering the uneven ground of the roadway, the present invention also hinges a turnable turning beam 4 or telescopic beam I at one end of the base 1, and a towing hole or towing ring for connecting an external towing device is provided at the other end. During transportation, as Figure 3 shown, the bottom surface of the turning beam 4 or telescopic beam I can contact the roadway floor. The turning beam 4 or telescopic beam I can increase the grounding area of the base to prevent tipping. At the same time, the turning beam 4 or telescopic beam I can adjust the inclination angle, which is suitable for transporting on the uneven roadway floor and avoids the influence of local obstacles on the roadway floor on the rapid displacement transportation.

[0038] Since there will be instability problems during disassembly and assembly of the single-column structure, the present invention further provides a support leg 5 on the base 1, so that the support leg 5 extends further along the length direction of the base 1 for a certain distance. The support leg 5 and the turning beam 4 or telescopic beam I are respectively arranged at both ends of the base 1. The support leg 5 preferably includes a connecting plate 51 and a support rod 52. One end of the connecting plate 51 is horizontally rotatably hinged to the base 1, and various choices can be made for the support position. The support rod 52 is vertically arranged at the other end of the connecting plate 51, and the support rod 52 is arranged on the connecting plate 51 in a liftable manner. When disassembling and assembling the support to be displaced, it is necessary to install the support leg and select a suitable support point by rotating the connecting plate in the horizontal direction according to the specific situation. During transportation, the lower end of the support rod needs to be separated from the supported roadway floor, which is more convenient for realizing rapid transportation. The support rod 52 adopted by the present invention can be a lead screw structure, which is threadedly connected to the connecting plate 51. Of course, the support rod 52 can also be a support jack, which is also connected to the free end of the connecting plate, and the support height of the connecting plate 51 is adjusted through the lifting action of the support rod 52.

[0039] In addition, the main frame 3 not only includes a main beam 31, but also a telescopic beam 32 is provided on the main beam 31. The side of the main beam 31 is used for detachably fixedly connecting with the support to be displaced 6. A fixed hinge structure can be provided on the main beam 31, or a hinge structure for detachably connecting with the main beam can be provided on each support to be displaced.

[0040] As Figure 2 and Figure 3 shown, the specific method for disassembling, assembling and transporting the hydraulic support is as follows:

[0041] Step 1: Move the folding support transportation device close to the support to be displaced, flip the flipping beam or telescopic beam I to a state in contact with the roadway floor, and at the same time adjust the support rod on the support leg to a state in contact with the roadway floor. Control the folding jack to extend so that its end is hinged to the upper part of the support to be displaced, and hinge the lower part of the support to be displaced to the base. When a main frame hinged to the folding jack and the base is provided on the transportation device, form a fixed connection between the main frame and the support to be displaced through a fixed connecting member.

[0042] Step 2: Control the support to be displaced to contract so that its upper end disengages from the roadway roof.

[0043] Step 3: Control the folding jack to contract so that the support to be displaced rotates from the vertical to the horizontal, reducing the overall transportation center of gravity.

[0044] Step 4: Through external traction, drive the folding support transportation device and the support to be displaced to move to the installation position together.

[0045] Step 5: Control the folding jack to extend so that the support to be displaced rotates from the horizontal to the vertical.

[0046] Step 6: Control the support to be displaced to extend so that its upper end forms an effective support with the roadway roof.

[0047] Step 7: Disconnect the fixed connection between the folding support transportation device and the displaced support, and complete the disassembly and assembly process of the support to be displaced.

[0048] Repeat the above steps and perform the support displacement in a large cycle mode in sequence.

[0049] The folding transportation device provided by the present invention can play a role in fixing the support to be displaced and maintaining its stability during the installation support and unloading support processes of the support. Through the support legs and the flipping beam or telescopic beam I at both ends of the base, the stability of the transportation device itself is further improved. At the same time, during transportation, the support to be displaced is adjusted from the vertical state to the horizontal state, reducing the center of gravity and transportation height of the support, improving the transportation stability of the support, and adapting to lower roadway transportation conditions.

[0050] Obviously, the above embodiments are only examples for clear illustration and not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
